Examples of org.apache.commons.cli.Options

org.apache.commons.cli.Options

Main entry-point into the library.

Options represents a collection of {@link Option} objects, whichdescribe the possible options for a command-line.

It may flexibly parse long and short options, with or without values. Additionally, it may parse only a portion of a commandline, allowing for flexible multi-stage parsing.
